I was going to get some footage of this before reporting it but then I died because of it so I really want it to be fixed ASAP. Sometimes while walking up stairs or slabs you get stuck on it for a bit. While on PG I fell out of the world because of this. Also, while flying with an elytra, you randomly get pushed downwards in what feels like steps. This killed me yesterday on the way to Auru. Also at roughly the same time another player was killed by that, I was kicked out of a boat. I think it comes in spikes which affect all players on the EU ip.
